A new method for the quantification of ambient particulate matter emission fluxes - Data

<p>An inversion method has been developed in order to quantify the emission fluxes of certain aerosol pollution sources<br> across a wide region in the Northern hemisphere, mainly in Europe and Western Asia. The data employed are the aerosol<br> contribution factors deducted by Positive Matrix Factorization (PMF) on a PM2.5 chemical composition dataset from 16<br> European and Asian cities for the period 2014 to 2016. The spatial resolution of the method corresponds to the geographic<br> grid cell size of the Lagrangian particle dispersion model 5 (FLEXPART 10.4 , 1 x 1 degree) which was utilized for the air mass backward simulations. The area covered is also related to the location of the 16 cities under study.</p>
